From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

On my system (Arch), if I have too much running, the kernel can kill processes based on resource starvation. It's quite possible you're running into a similar limitation. There should be a message in dmesg when this happens.
No, if you open a terminal and run:
sudo dmesgYou should get a long output which is the kernel log. Assuming the crash happened recently, there may be something in the last few lines (bottom of the output) which could indicate why the process died (or was killed). Keep in mind that this is a running log; so, if it's been a while since the crash, the entries for it may be higher up in the log. It's often best (if you can) to trigger the problem then immediately go run the
sudo dmesgcommand and look at the output. With luck, there will be useful logs. If not, you may need to look elsewhere.
